Caramelized Onions
Here is the basic technique for caramelizing onions. The next step is to toss in a little balsamic or sherry wine vinegar. Serve on top of mixed greens with crumbled blue cheese or as a side dish.
4 tbsp. unsalted butter or extra virgin olive oil (butter if making soup)
4 large onions, thinly sliced (use red for the salad, white for soup)
1 small sprig fresh rosemary or fresh thyme
2 to 3 tbsp. balsamic or sherry wine vinegar, or to taste
Pinch of sugar, or to taste
Salt and freshly ground black pepper, to taste
